I am new at dental billing. I am trying to figure out how to post primary and secondary insurance payments but me predecessor didn’t always post it the same way so I can’t figure it out that way. In medical billing you take the insurance adjustment from the primary insurance and not the secondary insurance. When I tried to google how to apply the primary and secondary insurance payments I got various, conflicting answers. So my question is how am I supposed to post primary and secondary payments? Which adjustment am I supposed to use?
